Description

Technical Field

[0001] The invention relates to the technical field of tea production, in particular to a rolling mechanism and a rolling method for withering tea leaves. Background Art

[0002] Rolling is the initial shaping process of tea leaves. It forms a tight and curved shape and also affects the internal quality. Rolling can tighten the tea leaves and reduce their volume, laying a good foundation for frying and drying them into strips, and appropriately destroying the leaf tissue and material transformation. Tea leaves are mostly rolled using rolling machines.

[0003] The rolling of tea leaves is achieved by pushing the tea leaves through a circular motion of a material barrel. The tea leaves interact with the ridges on the bottom of the rolling plate and then are rolled. Black tea needs to be fermented, so the original leaves of the black tea need to be damaged to a certain extent, while the shape of green tea needs to be protected as much as possible. Therefore, the ridges of the rolling machine for rolling black tea need to be higher than those of the rolling machine for rolling green tea, so the application range of existing rolling machines is relatively narrow.
